SILK-FINISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 670,749, dated March 26, 1901.

Application filed March 20. 1900. fierial No. 9,374. (No model.)

To all whom, it may concern:

Be itknown that I, JOSEPH WHITE, a citizen of the United States, residing in Paterson, in the county of Passaic and State of New J er sey, have invented certain new and useful Improvements in Silk-Finishing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

This invention relates "to machinery for finishing textile material, and especially silk goods; and it has reference particularly to that portion of an apparatus of this nature which accomplishes by a sort of calendering process the finishing proper.

The invention consistsin the improved finishing-machine and in the combination and arrangement of its various parts, substantially as will be hereinafter pointed out, and finally embodied in the clauses of the claim.

I have fully illustrated my invention in the accompanying drawings, wherein corresponding letters and figures of reference indicate like parts, and wherein- Figure l is a view in front elevation of my improved finishing-machine, portions thereof being broken away. Fig. 2 is a view in elevation of the left side of said machine. Fig. 3 is a view in elevation of the other side thereof, and Figs. 4 and 5 are respectively a top plan view and a vertical sectional view of a certain combined shaft-bearing and coupling mechanism constituting a part of my improved machinery.

The frame of the machine consists of two side standards Cb b, each surmounted by a vertical upright c, said standards being connected at the front and back of the frame by braces (Z. From each upright cand bolted thereto extends forwardly a horizontal support e, constituting a part of the frame. 2 is a brace for these arms.

fdesignates shafts or trunnions which are journaled in suitable bearings g, which surmount the standards a, and h denotes a drum that is carried by said shafts. To one of the heads or ends of this drum is secured a gearwheel 1 The uprights c are provided with vertical slots j, (seen in Fig. 1,) said slots being adapted to receive securing-bolts In, which project from bifurcated blocks Z and which are provided with nuts m, that are adapted to bind against one face of the upright, while the blocks bind against the other, thus firmly securing the latter in place.

a designates arms, each of which projects into a bifurcation of one of the blocks, (it should be remarked that the blocks are bifurcated horizontally,) being adapted to be removably secured therein by a pin 0, which penetrates the connecting ends of the block and arm. Each arm includes as a part of its structure a horizontal sleeve p. Each set of parts just described constitutes one of a pair of bearing-brackets for a cylindrical roller q, whose trunnions r are j ournaled in the sleeves p of corresponding bearing-brackets. The several bearing-brackets carried by each upright being disposed the one above the other and being movable ins-aid upright by simply" releasing their secnring-bolts,1 provide means for adjusting them relatively to each other, which consists of a series of bolts 8, vertically arranged in contact with each other end to end, the lowest one of the series resting upon one of the supports 6 and each being screwed into the free end of one of the arms a; By manipulating these bolts the rollers can be adjusted relatively to each other with the greatest facility.

On the trunnions r, at one end of the rollers q, are arranged intermeshing pinions i. The lowermost one of the rollers is also provided at its other end with a pinion a, which is operatively connected with the gear 'i so as to be driven thereby and drive the rollers through the medium of gearing 1), carried byasuitable bracket w, which is sustained upon theadjacent support 6.

From the rear faces of the upright 0 project brackets 00, which provide bearings for the trunnions of another roller y, said roller being provided With a pinion 2, which is also driven by the gear 11 through the medium of gearing 1, journaled in a suitablethracket 2, which is sustained upon the adjacent one of two angle-webs 3, integrally connecting the standards and uprights and bracing the latter.

4 designates a pair of arms which project from the brackets and carry supports 5 for the trunnions of rollers 6. Each of these rollers consists of a series of segmental sections 7, carried upon the ends of spring-actuated contractile spokes 8. They are commonly known as expansion-rollers, serving to exert a tension upon the goods which passes over them.

I 9 is a roller which is journaled in a pair of the supports 5, that is disposed near the ends of the arms 4.

1O designates a horizontal shaft which is journaled beneath the drum h in the standards a, and also in an auxiliary upright 11, disposed at one side of the machine. Between the two standards a b and adjacent the one which is the nearer to the upright 11 is secured upon the shaft 10 a gear 12, which is in mesh with the gear 2, which the drum carries. Outside of the standards I), and also carried by said shaft 10, is a pinion 13, which is in mesh with another gear 14, carried upon a short shaft 15, which is journaled in the upper end of the upright 11 and in the standard b. The shaft 15 also carries a pulley 16, over which passes a belt 17.

-18 designates the take-up roll, the same being driven bya shaft 19, which is journaled in one of two bearing-brackets 20, adj ustably mounted upon the ends of the supports 6. The end of the shaft 19 which is adjacent the pulley 16 is extended beyond the adjoining bracket 20 and carries a pulley 21. Its ex tremity is sustained by an auxiliary support consisting of a standard 22 and a rod 23,

mounted in said standard, a bearing-block 24, adjustably carried at the upper end of said rod, receiving said end of the shaft.

25 is a lever which is suspended from an integral outwardly-projecting sleeve 26 of the bracket 20, said lever abutting against a collar 27 on the shaft and carrying at its lower end a pair of small pulleys 28. The belt 17 passes under these two pulleys and then over the pulley 21, as best shown in Fig. 2. In order to adjust the lever 25, thus altering the position of the pulleys 28, so as to compensate for alterations in the length of the belt, a hand-wheel 29, mounted on and engaging the threaded end of a spindle 30, which is pivotally connected to the lever and is guided in a bracket-31, extending from the adjacent standard, is provided. In order that the jar ring of the machine will not operate to move the lever 25 by loosening the hand-wheel 29, I provide a binding-screw 32,which is mounted in the fulcruming portion of the lever and is adapted to take against the sleeve 26.

The roll 18 is provided with a squared shaft 34, one end of which is rounded, as at'35, and journaled in the bracket 20, being the one shown in Fig. 3. Near its other end this shaft is provided with a circular collar 36, which has bearings in a disk 37, that is secured against the inner face of the bearing portion of the bracket 20, being provided with a vertically-extending recess 38, open at the top, in which the collar seats. The disk is secured to the bracket by means of, preferably, screws 39. It should be remarked that the diameter of the collar is that of the diagonal thickness of the shaft. The end of the shaft 19 which is adjacent the shaft 34 is provided with a squared recess 40 of such size as to snugly fit the squared end of said shaft 34.

41 is a slot formed in the top of the bracket 20 and communicating with and being of substantially the same width as the recess 40.

'42 is a lock-screw which is mounted in the bracket and engages an annular groove 43, formed in the shaft 19, and 44 is a washer which spaces the lever 25 from the body portion of the bracket.

45 represents vertical steam tanks or cylinders, which are arranged one at each side of the machine, being secured to the uprights by means of stays 46, projecting from the latter. One of these cylinders is connected with a source of steam, hot-air, or hot-water supply by a pipe 47. These cylinders are connected with the various rollers q and g, which are hollow, through the medium of a series of piping 48 and the trunnions of said rollers,which, it should be remarked, are also hollow.

49 represents packing-glands, which serve as tight joints between the ends of the trunnions and the piping. It will be seen that the cylinders are tapped, as at 50, so that, if necessary, more rollers than those shown in the drawings can be accommodated in the machine. The ends of the shafts or trunnionsffor the drum h are likewise connected with the cylinders 45 through the medium of piping 51 andsuitable packing-glands 52.

At 53 in Fig. 3 I have shown a safety-valve attachment for the system of piping, rollers,-

&c., which is mounted, preferably, upon the piping at one end of the drum h. The lower ends of the cylinders 45 are provided with petcocks 54, beneath which are drip-pans 55,having waste-pipes 56. By this means any condensation in the cylinders may be drawn off as occasion requires.

Across the front of the frame of the machine and in the lower portion thereof, connecting and bracing the two standards, isa rigidlymounted shaft 57, one end of which projects beyond the frame and is threaded, its thread ed portion carrying and engaging a handwheel 58, which abuts against a spacing-sleeve 59 between said hand-wheel and the tubular portion of a bracket 60, said bracket being spaced from theadjoining one of two arms 61, which carry the shaft 57,by a spiral spring 62, coiled about said shaft. The bracket 60 has a vertical post 63, upon. which is swiveled a stand 64, in which is journaled one end of the main drive-shaft of the machine, and also one end of another shaft 66, said last-named shaft carrying a hand-wheel 67 and being threaded.

68 is another stand, similar in all respects to the stand 64, with the exception that it is swiveled upon the vertical stud 69 of a stationary bracket 70, which projects from the frame. In this stand are jonrnaled the other ends of the two shafts 65 and 66. The shaft 10 carries a friction -disk 71, while opposite said friction-disk and adapted to bear against the face thereof is a friction-wheel 72, which is keyed upon the shaft 65 and is loosely engaged by a fork 7 3,the body portion of which is tubular and receives and engages the threaded portion of the shaft 66.

7i represents fast and loose pulleys, which are mounted on the drive-shaft at one end thereof, and 75 is a shifting-fork for operating the belt that is adapted to be passed over said pulleys. This fork is mounted upon one end of a squared shaft 76, which is supported in uprights '7 7, that are carried by the stands 64 .68, said shaft having an operating-handle 7 S.

I have found it desirable in order to steady the action of the drum and of the roller y in revolving to provide a band 79, which is secured to a stud 80,projecting from the bracket 70, and passes over the trunnion of the roller 3 and is controlled at its free end by a weight 81, said band bearing against the periphery of the drum. In order to steady the rollers q, I provide a bracket 82, which projects from one of the uprights and carries an adj ustable vertical rod 83, that is provided with a shoe of leather or other similar material which bears against the periphery of the trunnion of the upper roller q.

84 designates aband of some suitable woven or other similar absorbent material that surrounds the drum h. It is against this band that the goods being treated contacts in passing around the drum.

The goods to be treated are introduced into the machine from the receptacle in which they are impregnated with the sizing or other finishing substance first under the roller 9, then over and under the expansion-rollers 6, then over the roller 3 around the drum h, and then back and forth around the several rollers q onto the take-up roll 18. The ex pansion-rollers 6 are of course, as is usual, properly adjusted before the machine is started in order to so act upon the goods as to obviate the tendency thereof in its moist condition to stretch unevenly, producing a bellying in the finished material. The belt-shifter being moved so as to dispose the belt on the driving-pulley and the hand-Wheel 58 having been manipulated so as to force the stand inward against the tension of the spring62 and swing the shafts and 66 about their fulcrum on the bracket 70, thus bringing the friction-wheel 72 in operative engagement with the friction-disk 71, the shaft 10 will be rotated. Of course the speed at which this shaft rotates can be regulated by simply manipulating the hand-wheel 67, so as to shift the friction-wheel radially with reference to the friction-disk. Through the intermeshing gears 12 and t' the rotation of the shaft 10 is imparted to the drum h, and simultaneously through the gearing comprised in the pinion 13 and the gear Z the shaft 15 will be rotated, said shaft in turn imparting its rotation to the shaft 19 through the pulleys 16 and 21 and the belt 17, connecting said pulleys. As

the shaft 19 rotates its motion is imparted to the take-up roll 18 through the mechanism shown in Figs. 4 and 5 and hereinbefore particularly described. Also as the drum revolves the roller y and the series of rollers q are respectively driven by said drum through the medium of the systems of gearing 1 and o. The several rollers q and y and the drum h are while rotating kept constantly heated by the steam, hot water, or hot air,'whichever is used, that is kept circulating through the system comprising these parts and the piping and vertical cylinders.

It will be observed that the several rollers q are not only adjustable relatively to each other,but they maybe removed with facility,so as to alter their number or in order to substitute them for others should occasion require.

By providing the arrangement of shaft connection and mounting shown in Figs. 4 and 5 the two shafts are not only effectively coupled together against unintentional disengagement, but they may be readily uncoupled, if such be the purpose, if the several parts be merely first made to assume such a relative dispositionnamely, with the recess 40 and slot 41 registering-that the end of the shaft can be lifted out of said recess.

It should be remarked that the roller y is designed to effect the setting, the drum h the drying and final even distribution, and the several rollers q the ironing and lustering of the finished substance. In other words, the finishing substance having been applied to the goods it is thereupon first evenly distributed throughout the length and breadth thereof by the roller g, which for this purpose presents a smooth unyielding surface. The roller y being heated, the material leaves it, with the finishing substancefset thereon,

in a partially-dried state and of course with l the most of it pressed through onto the face of the fabric awayfrom the roller, whereupon the material passes around the drum y with this face in contact with the absorbent belt thereon, which belt then acts to complete the drying out of the finishing substance. The belt on the drum not only completes the drying, but perfects the distribution of the finishing substance, this time with reference to the thickness of the goods and with regard to both its faces, whereupon the finishing substance having become thus perfectly set i in all respects it is ready for the calendering or polishing process which the heated rollers q afford. It is to be noted that did both the roller y and the drum present hard polished surfaces to the material, while a setting IOO might be effected by the one and a drying out by the other, such setting would be imperfect, for the finishing substance would at first be pressed through onto one face of the goods and then when it first contacted with the second polished surface immediately forced back again, so that by the time it reached the rollers q it would still be principally upon but one face of the goods. Hence the subjecting of the goods first to a hard polished surface and then to a somewhat yielding and less compact one is of importance in that thefinal setting exists in a uniform state with reference to the thickness of the goods as well as with reference to its length and breadth. At least the finishing substance gets time to dry sufficiently before it can be pressed back through the goods, so as to exist in a greater quantity on one face than on the other. By virtue of its covering the drum halso assists the roller y in effecting a uniform distribution in the fabric of the finishing substance.

It will be observed that in the use of my improved finishing-machine the goods is at no time under the pressure of two rollers. Only one side of the goods at any single point therein is at any time acted upon as it passes around the several rollers. The advantage of this is that the goods itself remains in practically the same state after it has passed through the machine in which it is when first introduced into the same, the fibers changing in the minimum their original relative disposition or character. The sizing or other finishing substance is simply applied to the goods, evenly distributed and dried on the same, and then ironed or given the luster, so that, in fact, the goods practically has no contact with the rollers Whatever, the finishing substance beinginterposed. In treating goods having an edge or selvage thicker than its body, however, as where the body of the goods, for instance, is silk while its selvage is cotton material, in order to reduce the thickness of the edge portion and make it like that of the body of the goods the several rollers q may be brought close enough together so as to effect this by compressing simply said edge or selvage portion of the goods.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
